The Democrats’ “Great Freshman Hope,” Sen. Kamala Harris, is heading to the Hamptons to meet with Hillary Clinton’s biggest backers.

The California senator is being fêted in Bridgehampton on Saturday at the home of MWWPR guru Michael Kempner, a staunch Clinton supporter who was one of her national-finance co-chairs and a led fund-raiser for her 2008 bid for the presidency. He was also listed as one of the top “bundlers” for Barack Obama’s 2012 re-election campaign, having raised $3 million.

Guests there to greet Harris are expected to include Margo Alexander, a member of Clinton’s inner circle; Dennis Mehiel, a Democratic donor who is the chairman of the Battery Park City Authority, even though he lives between a sprawling Westchester estate and an Upper East Side pad; designer Steven Gambrel and Democratic National Committee member Robert Zimmerman.

Washington lobbyist Liz Robbins is also hosting a separate Hamptons lunch for Harris.

Harris, a 52-year-old former prosecutor and San Francisco district attorney who went on to become California’s attorney general, was a star of the Senate intelligence committee hearing into President Trump’s ties to Russia, grilling US Attorney General Jeff Sessions. Harris has also opposed 18 of Trump’s 22 administration nominees.

Plus, in 2013, former President Obama had to apologize after telling a group that, in addition to being “brilliant,” “dedicated” and “tough,” Harris “also happens to be, by far, the best-looking attorney general in the country.”

Despite being less than seven months into her new job as senator, Harris is already said to be the Democrats’ top fund-raiser and is being talked about as a 2020 presidential hopeful.

Harris has denied having “national aspirations,” but this Hamptons trip proves it isn’t far from her mind.

A Democratic insider said, ­“Kamala is the big Democratic star right now, at a time when they badly need a star. She’s coming to the Hamptons to meet key people as she takes a national stage, and expands her influence and ambitions.”
